I am one of those that actually dislike the use of calculators in school.

During highschool we had to use calculators because the answers could not be described as a fraction 3/7 or an angle of 2*PI etc.

As soon as I enrolled at the university there was not even one subject that required a calculator. All the problems had a solution that could solved by hand even if the actual problem was way more complicated than anything we had ever done in highschool.

When looking back I came to the solution that the required use of calculators in highschool only added to the confusion when trying to understand math. I can not understand why the hell we had to use them because it is so much easier to understand math if not having to rely on the calculator to solve your problem.
